Not really it's like 90% luck and 10% spamming alley oop calls when u have the on court coach badge and purposefully not going for alley oop but letting it sail out of bounds and try to trigger animation. It is very random and there's no guarantee you'll trigger the loose ball save animation when going for it. A lot of times ball is already out of bounds when he attempts to dive. I can say I got it by luck and no skill whatsoever. Whwn the opportunity presented itself, I would spam X and Y.
